**AntiScam Pro** is a modern, open-source security toolkit designed to detect **phishing, scam, and spam** in messages, phone numbers, and URLs.  
It combines **AI-powered analysis (BERT)**, **heuristic detection**, and **VirusTotal integration** to deliver precise, transparent, and explainable results.

---

## ✨ Key Features

- 🤖 **AI-powered message classification** – fine-tuned BERT model detects phishing or spam text.  
- 🔗 **Smart URL inspection** – resolves redirects, short links, and checks domains via VirusTotal.  
- 📞 **Phone number validation** – detects known or suspicious scam numbers.  
- 🌐 **REST API + Web UI** – interact easily from a browser or programmatically.  
- 📊 **Session & global statistics** – track analysis metrics over time.  
- 🔒 **Privacy-first design** – no data is stored or sent externally.  

---

## ⚙️ Installation

```bash
git clone https://github.com/zvspany/antiscam-pro.git
cd antiscam-pro
pip install -r requirements.txt
```
If you want to enable **VirusTotal integration**, create `.env` file in the project root:
```
VIRUSTOTAL_API_KEY=your_api_key_here
FLASK_SECRET_KEY=change_this_secret
```
Then run the app:
```
python app.py
```
Access the dashboard at:

## 💬 Usage
**You can use AntiScam Pro either from the browser UI or the API endpoints.**

---

## 🧠 How It Works
AntiScam Pro applies **multi-layered analysis** for high accuracy and interpretability:
  **1. Input Validation** – detects whether the user provided a message, URL, or number.
  **2. Heuristic Filters** – scans for known scam keywords, shorteners, or flagged domains.
  **3. AI Classification** – BERT model predicts whether text is phishing, spam, or safe.
  **4. External Intelligence** – optional VirusTotal API check for additional reputation data.
  **5. Decision Fusion** – merges signals into a single final verdict.
This architecture ensures both **speed** and **transparency**, making it suitable for research and production use.

---

## 🧰 Tech Stack
- **🐍 Python 3** + **Flask** – lightweight and fast backend
- **🤗 HuggingFace Transformers (BERT)** – machine learning for text analysis
- **🌍 Requests** – robust HTTP handling
- **🧩 VirusTotal API** – optional link intelligence
- **⚙️ Regex** + **heuristic rules** – simple but effective early filtering

---

## 🪶 Design Philosophy

AntiScam Pro is built around four core principles:
**🕵️‍♂️ Transparency** – detection logic is fully open and auditable
**⚡ Simplicity** – lightweight, minimal dependencies
**🔐 Privacy** – no user tracking, no telemetry, no cloud sync
**🧩 Extensibility** – easy to add models, blacklists, or new APIs
